Never one to rest on its laurels, Nikon has taken the already highly-rated 12.4 megapixel D2X digital SLR and tweaked several features that are probably very important to professional photographers (but mean little to the rest of us) to come up with the new D2Xs. The major enhancements to this model include an improved 2.5-inch display, longer-life battery, the addition of a black and white mode, Adobe RGB support in all color modes, and better viewfinder performance; other, less exciting improvements are a new menu color scheme, extra 1/3 stop ISO settings, more Custom Curve options, and electronic viewfinder masking in High Speed Crop mode -- we can't even tell you how long we've been waiting for this last option. Making the best even better usually doesn't come cheap, though, but the D2Xs will only set you back a pretty reasonable $4,700 when it's released next month.
